To all whom t may concern:

Be it known that I, LoUIs F. CLAUsiNG, a citizen of the United States, and resident of Burlingame, county of San Mateo, ,and State of California, have invented a new and useful Heater, of which the following is a specification.

The present invention relates to improvementsl in gas heaters and the principal object of the invention is to provide a gas heater that has a maximum amount of radiating surface in as little space as possible. A further object of the invention is to provide a heater of the character described in which the burned gas comes in no wise in contact with the air of the room to be heated, but is only used to heat a large radiating surface, whereupon it is guided int-o a smokestack. A further object of theinvention is to provide heat radiating means particularly adapted to receive heat units from the burning gas over al large area and to allow the air to be heated to pass over its outer surface, thereby transmitting the heat units received immediately to the air tobe heated.l

With these objects in View, l have illustrated the preferred form of my invention in the accompanying drawing, in which Figure 1 represents a vertical cross section through my heater; Figure 2 a top plan view of the same and Figure 3 a horizontal sectiony through the same along line 3--3 of Figure 1,

While the drawings show only the preferred form'of the invention, 1 wish to have it understood that various changes or modi-l fications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

My heater comprises a preferably rectangular housing (1) provided with outwardly extending flanges (2) at its top.l My de- -vice is designed to extend downwardly from the lfloor of the room to be heated and it is supported on the oor by means of the flanges (2). The flanges are preferably arranged relative to the ioor in such a manyner that the perforated cover (3) lfor the housing is substantially flush with the floor. The bottom of the housing is flanged inwardly as shown at (4)' and supports the bottom plate (6) which is provided with a large central hole (7) adapted to receive the radiator (8) which is secured to the flange (9) extending downwardly from the 5:5

bottom plates by means of suitable bolts (11).

It will be seenv from the drawings that the principal portion of the radiator is enclosed by the housing, while a somewhat reduced portion extends below the same. rThe particular shape of the radiator is the most essentialpart of my invention. It is preferably made of corrugated sheet metal. The corrugations, however, are of considerably larger dimensions than is usually the case.

A strip of this corrugated metal is turned into preferably tubular form so that the corrugations are disposed vertically. lt will be readily understood that in this manner a tubular central space (16) is provided with 70 which communicate a rather large number of channels formed by the corrugations. These channels (17) adjoining the central space will be hereafter referred to as' the inner channels as contradistinguished from the outer channels of the radiator which communicate directly with the space between the radiator and the housing. rThe radiator is closed on top, which is effected by covering the central space with a suitable cap (18) and by closing the inner channels which is preferably done by welding the upper edges defining the inner channels together. In a similar manner the outer channels (19) are closed at the bottom` so that 85 there is no communication whatever between the inside of the radiator and the housing while the 'inner channels connect directly with the lower portion of the radiator and the outer channels directly with the upper portion of the housing.

rlhe burner (21) fed by the pipe (22) may be of any desired construction and is enclosed by a pipe (23) extending Iinto the ra` diator through a desired distance suflicient to guide the products of combustion into the interior of the radiator and to avoid any interference of ventilation currents with the direct rising of the said products. The

pipe (23), is supported by means of a second 100 an outlet (27) leading preferably into the 105 chimney. rlhe structure is ope'n at the bottom and prevents too much draft from passing over the burner.

The top plate (3) has a downwardly eX- tending ange (3l)4 to which is secured a large tube (32) which extends downwardly so as to cover a considerable portion of the radiator as shown in Figure l.

The operation of my gas heaterv will be easily understood. The products of combusf. tion are carried upward inside the vpipe (23), its open bottomproviding ample ventilation, and rises in thev central portion ofv the radiator until it arrives near the top ofA the latter.` A draft 'is created through the pipe (27) during this process, whereby air will be drawn from the space surrounding the pipel (23) into the chimney. Since this ydraft affects only the outer portion ofthe f lower part of the radiator, the inner portion being protected by the pipe (2 3), a partial 'vacuum is created 1n the inner channels,

whereby the products of combustion which 4 have risen to the top in the centralwportion any considerable extent the air enclosed between the tube (32) and the housing.'

Whilethis air rises through the perforated top plate it naturally .creates a partial vacuum in the lower portionsof the outer channels and this vacuum will be filled from the air outside the tube (32) so that a natu'- ral circulation is created, the hot air rising in the outer channels and the cool air coming L tion 'is rapidly transmitted to the outer channels through the medium of the corrugated radiating surface from where'it rises into the room to be heated while cool air is simuln taneously withdrawn from the same room and fed into the outer channels.

My'device is not confined to the form illustrated in the drawings. It will be understoodV that the same' may be placed on the floor of the basement like a furnace, in which case communication between the room to be heated and the heater is established by the use of proper pipes. The register or perforated cover (3) may also be disposed in the wall of .the rooms to be heated, in which case the heater "is placed underneath the wall and connected directly to the registerboX.

I claim: I

l. In a heater of the character described, a radiator comprising a strip of corrugated sheet metal bent into tubular form so as to present innerland outer channels, the-walls defining the outer channels being joined at bne end and the walls defining the inner channels being joinedat the other end. A 2. In a heater of the character described, acne-piece radiator comprising a strip of corrugated sheet metal bent into tubular form so as to present inner and outer channels, the walls defining the outer channels being brought together and joined at one end and the walls defining the inner channels being brought together and joined a the other end.
